Allow Specific Days to be selected for Invoices and Recurring Plans
Centers need to be able to select specific dates for generation and due dates for invoices and recurring plans. Currently, the 1st-10th can be selected, then the 15th, then the 10th to the last - the last day of the month.
This center has many possible charges in their recurring attendance plans, and it's overwhelming for them and parents to see all of the charges when many of them are $0. They'd like $0 charges to be hidden from the invoice and from reporting.
